No I can't explain it but the value is used in only one place, and a few
lines further up it calls glDisable(GL_POLYGON_SMOOTH) which disables
point antialiasing, and in that condition the value gets rounded to  
an integer.
This could be zero or one, but it says if it is zero it gets replaced  
with one,
so according to my reading of the documentation it will use the value  
one
anyway so its all very pointless ( no pun intended ).
